Abstract
A wheelchair seatback assembly suitable for detachable mounting to the back-supporting posts of a wheelchair. The back assembly includes a relatively rigid shell member carrying post-engaging pins and a plurality of mounting clips attachable to wheelchair posts. At least selected ones of the mounting clips are further formed to releasably engage the post-engaging pins. The mounting units are also formed for single-handed automatic unlocking and release of the pair of hooks from the mounting units and posts upon rotation of the shell member forwardly over the wheelchair seat by an amount in excess of any displacement occurring during normal use of the wheelchair.
